And that’s not how you establish a PKI or implement AE (authenticated encryption).
When I send a voice message e.g. I don’t verbally sign it, that’s actually part of KE (key exchange) protocol.
Same applies to non encrypted, authenticated communication of course.
And in case you are talking about physical face to face communication: I think you’d recognize your family and friends without the help of cryptography.
Of course you don’t verbally sign voice messages. That wouldn’t make any sense at all unless you are a robot or something.
It was just a joke. But if you wanted to authenticate something (like an email, or voice I guess) in a PKI you would sign it using your certificate private key and the CA would tell the recipient if it’s valid or not.

Yeah, I wouldn’t recommend doing that.

That’s what the article is about though, voice messages can now be spoofed. It happened to one of my friend’s parents

I was implying that you do the actual singing verbally. Like actually saying the bits and bob, which would be pretty much impossible.
Of course you could sign voice messages. That would be like singing any other file.
